Info in Breeding Oscars
for bro who r into breeding oscar...
this might help....
During their spawning process, they will use their mouths to clean a flat rock, and the female will lay her eggs there. Not all the eggs are laid at once; the female will take breathers, at which time the male moves in and fertilizes the eggs. A female usually lays 1,000-2,000 eggs. The eggs are opaque at first, turning transparent in 24 hours. After the eggs are laid, both parents watch over the eggs, wafting the eggs with their fin and guarding them against predators. Occasionally they take the eggs in their mouth, which keeps them clean and turns up bad eggs, which are then destroyed.
If a constant tank temperature is maintained, the eggs should hatch in about 36 hours. At first, the fry cannot swim, but they squirm "en masse" on the rock, living off the egg sac, for about 4 days. The parents constantly attend to their young at this time. Feeding these fry is easier than other breeds, because of the baby Oscar's relatively large size. A good and simple plan is to crush regular processed flake food in your fingers, and just drop it in. Turn off filtration during fry feeding time to make it easier for them to find their bits of food.
How the parents act towards their fry depends entirely on each fish personality. Some have numerous spawn and never bother their fry; others easily eat their young. To be on the safe side, you can separate the fry from their parents. However I do not recommend this until the parents have had a few unsuccessful spawnings. The fry will reach 1.5 to 2 inches after 12 weeks
